Android: Universal Image Loader and ProgressBar on ViewPager not working

Question

I have an adapter for a viewPgaer where I cache images with UIL on a ImageView. I never used a ProgressBar when loading an image and it is working just fine. I dicided to make and a progress bar but when I open the activity the progress bar is spinning and after a while it is gone like it should be but the image is not displayed and in addition I can't swipe to next images. I don't know what I am doing wrong. Thank you :)

ViewPager Adapter

@Override
public Object instantiateItem(ViewGroup container, int position) {
    TouchImageView imgDisplay;

    inflater = (LayoutInflater) _activity
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View viewLayout = inflater.inflate(R.layout.layout_fullscreen_image, container,
            false);

    imgDisplay = (TouchImageView) viewLayout.findViewById(R.id.imgDisplay);
    final ProgressBar spinner = (ProgressBar) viewLayout.findViewById(R.id.progressBarFull);

    DisplayImageOptions options = new DisplayImageOptions.Builder()
            .cacheInMemory(true)
            .cacheOnDisk(true)
            .considerExifParams(true)
            .bitmapConfig(Bitmap.Config.RGB_565)
            .imageScaleType(ImageScaleType.EXACTLY_STRETCHED)
            .build();

    ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(_activity.getApplicationContext()).build();
    ImageLoader.getInstance().init(config);
    ImageLoader imageLoader = ImageLoader.getInstance();

    imageLoader.displayImage(_imagePaths.get(position), imgDisplay, options, new SimpleImageLoadingListener() {
        @Override
        public void onLoadingStarted(String imageUri, View view) {
            spinner.setVisibility(View.VISIBLE);
        }

        @Override
        public void onLoadingFailed(String imageUri, View view, FailReason failReason) {
            spinner.setVisibility(View.GONE);
        }

        @Override
        public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
            spinner.setVisibility(View.GONE);
        }
    });

    ((ViewPager) container).addView(viewLayout);

    return viewLayout;
}

layout_fullscreen_image.xml

<?xml version="1.0" encoding="utf-8"?>

    android:layout_height="fill_parent"
    android:scaleType="fitCenter"
    android:background="#000000"/>

<ProgressBar

    android:layout_height="wrap_content"
    android:id="@+id/progressBarFull"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true"
    android:visibility="gone"/>

</RelativeLayout>
